Topic: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH - page 216. (Read 528055 times)

I missed getting an S7 B6 unit. I was gathering up some coins. Hopefully there will be a B7 before Chinese new year.

Here's a different spin on the S7 B6 unit:

1) 4050 GH/s, 135 chips

This works out to 4050/135 = 30 GH/s per chip.

Now to compare it to the S7 b1 batch, take 162 x 30 GH/s = 4860 GH/s.

So the fact that the B1 and B6 batch chips hash rate jibe means that you are most likely not getting any fallout or out of spec chips.

2) 135/162 = 0.83

So if the B6 and the earlier batches have the same footprint, is there a technical reason to cut down the power by 17%?:

a) If the majority of the 27 chips were removed from the middle board, this might point to a heat dissipation issue. The problem with this is the stocking of multiple boards.

b) If they were equally removed from each board, this might point to a some sort of board power bus issue.

c) Furthermore because the boards get warmer the farther away the air intake is, hopefully the missing chips are from the warmer end. Finally because each chip has it's own finned heat sink, less heat sinks mean better air flow.

d) Numerology: The fact that 27 is divisible by 3 most likely points to the fact that the B6 boards are missing 9 chips each.

e) Supply chain issue: Do you stock two different boards or just use the same board with 9 chips deactivated? The fact that BM didn't undervolt, underclock to get to 4050 with 162 chips may also say something.

What I did to help the noise is I placed a small foam piece covering the air intake maybe 10%-20% covered. I have not had any heat or noise issues.

I managed to pick up one for 1328$, just in time. this time , next day was sold out. wasn`t so lucky for a b5, by the time i had transfered fiat to BTC they had sold out the same day.

now i wonder like everyone else when and what B7 will be like.

semi-good...

, but I did score one B4B5 at btc $489  

for some reason couldn't wait another 20min...oh, well
lesson learned as bitcoin always hits the round numbers on the way up or down.

LOL   

Good one!  You got me there!

Unfortunately, I did not get any of batch 6.  I almost bought a couple of them but decided to wait until next month.  Hopefully, my patience will not serve me wrong.

In closing, I leave you Seinfeld:




Anyone else lock in some B6 miners for a good price?

I learned a lesson in this "slap fight" as well.  I've learned it's not even worth my time getting into one or starting one.  I'm probably more to blame for it getting started if in fact your statement was truthful about only mentioning it because you wouldn't spend that amount of money on it.  I probably took it the wrong way, unfortunately.

Forgive me for taking it the wrong way, hodedowe.

By the way, I'm not a "troll." And no, you're not ignored in perpetuity.

Thanks for the heads up on the APC PDU, wolfen!  Definitely worth getting that particular PDU "used" than getting the Tripp Lite "new."

Let's put this behind us, hodedowe.

Have a good evening, Sir.

This is exactly it. BTC dropped below $300/BTC and I'd imagine they saw a large portion of their profit running for the exits. That behind us, I'm excited to see the B7 model and whether or not it's ~4.8 TH again.







@ all the replies to the slapfight, hahah guys. Maybe I did get a little riled about posting an opinion and getting my ass chewed off. It was unexpected. I guess I poked the troll. Ignored in perpetuity now, won't happen again. 

How can I make my Antminer S7 remote control ?

But you didn't contract for an AFB in Georgia...  <- I'm not laughing, honest.

Anyway on topic, I caved in and bought a Batch 6. At 4 BTC I figure it's low risk and helps to ease the pain of Batch 1. Production issues should be sorted out by now, the specs have been downgraded, shouldn't have any major issues.

Most likely with it priced in dollars and NOT a fixed BTC price. It could even be just more of Batch 6 with a pricing change.

bitmain is contemplating pricing miners in gold-pressed latinum as nothing else keeps the value right 

Hopefully not until I have the BTC saved up to buy one!  I missed out on the last few batches since I blew over 6.5 on batch 3.

Well I make over $380K a year!  Seriously, anyone posting how much they make either has a major inferiority complex about themselves or they're simply lying and typing their message from mom's basement.

Has Bitmain released any information as to when there will be more products available?

How many people feel the need to post their annual salary on a bitcoin enthusiasts' message board? Something to prove, maybe? DMWard is one of the more chill guys I've dealt with on here. Have you considered trying Kegel exercises? I hear it helps with stress.

I can't think of any other reason for showing your rear on the internet. Unless you're just a jerk in general. The "laughing face" is a CHEESY face (mouseover it), It's smirky and fun, not "HA HA HA UR A FOOL OMG U SPENDED ALL UR MUNNIES UR CHILLINZ BE DYIN OF STARVATION HAHAHA". Lighten up and "Have a good day".

LOL, Now I've got to be having a bad day?  Really?  I'm at home with my 4 year old son.  I work when I want to [For the most part].  I'm far from having a bad day, Sir.

You are trying to justify the "laughing face" you put on your original response to me by being condescending and without giving any input in that response as to a potential easier and/or cheaper way of accomplishing what I'm wanting to do.  How am I supposed to take it?  Am I supposed to laugh too?  Then [After realizing your lack of tactfulness in your first response] you follow up with two other responses that are condescending in "tone."  I honestly believe your second response would have sufficed [Without the sarcasm of course].

Anyway, I'm done with this.

Have a good day, Sir.

Again, I think you read the entire first comment with the wrong tone. You're having an aneurysm over my saying I could never justify that type of expense - and this is from a guy that makes over $240k/year. If you want to, that's fine. Do it. But don't try to rip me a new one because you're having a bad day. If you can't play nice, play somewhere else.


And @wolfen, fantastic stable product. Amazon has them for 89 bucks too. I fiddled with three of those while contracting for an AFB in Georgia a few years ago.

If you have any questions configuring I have had to become very intimate with them.
Sometimes they ship with SSL installed and you have to use the serial port and putty on the front to set the IP address.
Happened on two of mine.
S5's were notorious for crapping out on nicehash. Was very nice to just click from my ipad in bed instead of driving two miles down the street to the datacenter or having the guys on call flip the switch.
Had to use it just once with the s7's.
